I am very interest to see the following in the new update of V5.

1) The introduction of GUMBALL into 3Dmoi because is very effective and easy way to manipulating the NURBS curves to change the orientation of points that you need to create.
2) The introduction of Orient command in 3 points (ORIENT3Pt). This orient command is very effective of 3 points to align an object to another object more easy way.
3) The introduction of essential SubD geometry Tools commands. They are very amaze creations that you can do with them.
4) I like to see an introduction of plug-ins in the 3Dmoi environment to have more abilities in 3D.

These are what I am thinking to see for the next creation of V5.
